Concern for Daughter’s Well-Being
You should file a motion to enforce the parenting agreement and request a modification of the parenting time. The court will most likely appoint a child and family investigator which is either an attorney or mental health professional to investigate and find out what is going on. They will interview everyone including your ex, your daughter, people close to her or who went to school with, teachers or counselors she may have known while attending school, you , your new spouse or family if you have one, and any other person they deem to be of interest to your situation. You can voice your concerns to the CFI. The CFI can recommend that she get a psychological evaluation or be evaluated for depression or anxiety and obtain the proper treatment, if any.
That is the only way you’ll be able to gain insight and knowledge as to what is really going on with your daughter.
